Adopted code
The Town of Granby has adopted the International Building Code, 2021 Edition, by reference as its building code (Granby Municipal Code Chapter 15.05), with local amendments including roof-covering provisions for ice barrier underlayment, drip edge, snow-shed barriers, and metal roof panel installation.
Drip edge
Required — The town's 2021 building-code amendment ordinance (Chapter 15.05.040, read in full) replaces Section 1507.2.8.3 Drip Edge: a drip edge is required at the eave and rake edges of all pitched roofs, with adjacent segments lapped not less than 1 inch, a vertical leg not less than 1 inch wide that extends below the sheathing/fascia juncture not less than 1/4 inch, extension back onto the roof deck not less than 2 inches, underlayment installed over the drip edge along eaves, and mechanical fastening at intervals not greater than 18 inches. About drip edge
Ice & water shield
Required — The town's 2021 IRC amendment ordinance (Chapter 15.05.050, read in full) adds Section R905.1.1 Ice Barrier: an approved self-adhering polymer-modified bitumen ice barrier is required in lieu of normal underlayment on all sloped roofs of habitable structures, installed from the eaves to a point 6 feet inside the exterior wall line and 24 inches from the center line of all valleys, fully adhered to the substrate. Detached accessory structures with no conditioned floor area are exempted. About ice & water barrier
Impact-resistant roofing
Not required — The town's 2021 building-code amendment ordinance (Chapters 15.05.040 and 15.05.050, read in full, including every roof-covering amendment) contains no UL 2218 or Class 4 impact-resistance provision and no roof-covering fire-classification (Class A/B/C) provision; its roof-covering amendments address only ice/snow performance (ice barrier, snow-shed barriers, sidewall flashing, mechanical snow barriers) and the re-covering/layer-removal rule.
Repair permit threshold
The town's 2021 IRC amendment ordinance (Chapter 15.05.050, read in full) amends Section R105.2 Work Exempt From Permit; its 13-item exemption list (small accessory structures, fences, retaining walls, small water tanks, grade-level walks/driveways, finish work, small pools, playground equipment, small decks, agricultural buildings, nonstructural siding repair, and gutters/downspouts/storm windows) contains no size- or value-based exemption for roof repair or replacement, so any roof repair or replacement work in the Town of Granby requires a building permit regardless of scope.
Wind design criteria
The Town of Granby's 2021 building-code adoption ordinance (Granby Municipal Code Chapter 15.05, read in full) sets a minimum design wind speed of 105 mph, Exposure B, for the town. The figure is stated twice in the same ordinance: once in the IBC amendments (Section 1609.1, "Minimum design wind speed is 105 mph with exposure category determined by Section 1609.4") and again in the IRC amendments (Table R301.2, listing "WIND SPEED IS ... 105 MILES PER HOUR EXPOSURE B").
Roof layer limit / recover
The town's 2021 IRC amendment ordinance (Chapter 15.05.050, read in full) amends Section R907.3 Re-Covering Versus Replacement: a new roof covering may not be installed over an existing one without first removing all existing roof-covering layers where the existing roof or covering is water-soaked or too deteriorated to serve as a base, where the existing covering is wood shake, slate, clay, cement, or asbestos-cement tile, where the existing roof already carries more than one application of any roof covering, or, for asphalt shingles, where the building sits in a moderate- or severe-hail area under IRC Figure R903.5.
Deck & sheathing requirements
The town's 2021 IRC amendment ordinance (Chapter 15.05.050, read in full) adds Section R803.2.1.3 Wood Structural Panel Sheathing Thickness: a minimum of 5/8-inch plywood, particle board, or wafer wood is required on roof rafters or roof trusses spaced 24 inches on center in any snow-load area, and wood structural panel roof sheathing must be bonded by exterior glue.
Sales & use tax
8.2% combined (state 2.9% + Grand County 1.30% + Town of Granby 4%; no RTD/SCFD/RTA district — Grand County is outside the RTD/CD boundary). Granby is a statutory municipality; sales tax is state- collected per Colorado Department of Revenue form DR 1002 (rev. 06/19/19; updated semi-annually). The Town's own Finance page independently lists the combined rate as "8.2%," corroborating the DR 1002 total. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
